A Word from the Builder

**25/12/2020 What started as a fourth submarine to try out some sub ideas I'd been musing on, morphed into a stay-at-home covid project. Some ideas had to be abandoned, some reworked, extensive learning experience of the editor. I used elements I liked from SS13 of traitors systematically subverting and defeating a station, and incorporated them into a large submarine. Some have confused this sub for a station, some inquired if I had a patreon to donate to, but I'm just here to walk that fun line between jolly cooperation and psychotic mayhem in the abyss. Many fun times with this game since first legacy release, and hope this sub helps spread the fun. Cheers and happy holidays. :]

GENERAL SPECIFICATIONS

**NO MODS REQUIRED : ALL BASE-GAME CONTENT !

Market Cost : 200000 MK Classification : Tier 3 Attack Sub Recommended crew size : 8 - 16 Recommended crew skill : Experienced Dimensions : 63m x 25m Max linear velocity : 40km/h Maximum Ascent : 17km/h Maximum Descent : 10km/h Total Hull Volume : 9116454 Optimal neutral ballast : 0.5847

Items are stock in performance (from the time it was created) with some exceptions:

• Main submarine chainguns have +50% firing rate, but consume +50% power

• Some components are "reduced equivalents" in an effort to reduce part count and signal calculation updates, e.g. the "Mega-capacitor" has the combined quality of 5 super capacitors (charge, repair time, etc), All changes are done with an effort to keep the sub "fair" in relation to stock component properties

• Item deterioration threshold set to 100%; Components in this sub only deteriorate when damaged by environmental elements or pushed beyond specifications. Lack of repair frequency offset by the large volume of items to repair in the wake of catastrophic events.

Large Station Reactor : 20,000 KW Output 2 Large Engines : 4,000 KW Load Max (each) Idle Power : ~5,500 KW Load (after all caps+batts charged, no thrust) Silent Mode Idle : ~2,500 KW Load Battery Reserves : 32,000 KW*min

3 Interior coilguns for repelling creatures, boarding parties, subduing mutiny, or traitorous mayhem 6 Discharge coils 2 Depth charge tubes, front+rear, mutually linked to 5 loaders 7 Exterior small turrets (4 available from docked Minisubs) 3 External railguns for rear, top, bottom cover 5 Frontal railguns, integrated cannon system with 3 firing modes : volley, single sequence, and salvo sequence

Design start : July 31, 2020 Design "end" : Dec 25, 2020 Estimated time in-editor: ~550 hours (and counting) x_x

FEATURES AND FUNCTIONS

** ** Designed for ease of use and balanced for Baro **

• Campaign ready : Ai can path to all areas of the submarine, even maintenance tunnels, and use all gun turrets

• Extensive refining : +500 hours of playtesting, feedback, QOL changes, rebalancing items, and grief deterrents without negating traitor mode gameplay

• Almost all of the submarine can be accessed on-foot without climbing

• Atmospheric lighting for normal operations, stealth mode, and power-outs

• Gunnery deck links Operations, Command, and Crew sections of the submarine with large and unbroken pathway

• Rooms requiring ID placed to avoid obstruction of main player pathways

• ID restricted areas and lockers highlighted with red symbols indicating access requirements

• Command has auto doors, all other doors on the submarine are manual. Flood hazard presented by open doors from careless crew, or deliberate traitors

• Large open areas to give the sub the feeling of being "big", while also decreasing the amount of compartmentalization available against flooding, to balance the sub's inane offensive capabilities

• External nooks around the sub for small enemies to wriggle into

• NEW 31/3/2021 : Maintenance tunnels around sub perimeter: buffer against flooding, but mostly to facilitate cat-and-mouse chases

• NEW 4/4/2021 : Brig now has flush/jettison execution system

** Navigation control suite **

• Room lockdown for every section of the submarine

• Reactor killswitch, flood (anti-fire)

• Silent Mode for reducing submarine sonar noise, reduces motor and ballast input, shuts down reactor and activates battery array

• Ship-wide status display system; default messages include (Clear), Caution, Alert, and Evacuate. Display components can be edited in-game for fun

• Head of Staff (HoS) equipment for delegating crew leaders and improving crew item access, priority item for traitors!

• 60 Second Self-Destruct sequence; Captain ID arms, 2 HoS or higher required for simultaneous button press to activate. Activation starts 60 second countdown, ending with a massive explosion

• Sonar-aimed five railgun cannon system with volley fire, sequence fire, and salvo sequence (25 rounds)

** ID access designed to emphasize class roles, traitor mode, grief deterrent **

• Structured ID access: cooperate and communicate in the use of critical items, while not letting them fall into the hands of traitors (or griefers)

• Captain ID grants full access

• HoS ID grants access to all class areas and containers, excluding the Captain's lockers in Navigation

• Mechanics control access to welding fuel reserves, have reactor and maintenance access

• Engineers control access to all fuel, have reactor and maintenance access

• Medics control access to all opiates and hazardous substances ; Captain or HoS required for Toxins.

• Security controls access to all weaponry and camera system ; Captain or HoS required for high grade weapons.

• Hidden items, spaces, and concealment throughout the submarine to aid traitors and troublemakers!

** First in Baro : Channel-select Camera Monitor System **

• Security room features camera system controlled by selecting rooms on a map display of the submarine. No flipping through channels on this sub!

• Selecting the security room locks the periscope from viewing cameras, to prevent non-security personnel from use

• Three (red) cameras along the main connecting deck have internal coilgun turrets for defense of the submarine from enemies within

• Blind spots throughout submarine, components+structures which offer concealment to assist sneaky traitors

** Four minisub fighters **

• Acts as gun-pod while docked, reducing power demands from docked vessel

• Command room light indicators to display whether or not a minisub is docked to a given port

• Main-sub exterior shaped to fit Minisubs, providing easy alignment for docking

• Double as evacuation shuttles, have traveled distances as far as 9000m!

• Features top and bottom coilguns for wide angles of covering fire

• Blast doors which shut when forward dome is ruptured

• Hardy minisubs capable of entering modestly sized passages
